Even if the csv isn’t being typed out by hand, when importing into Excel and the delimiter needs to be manually entered, because it isn’t one of the common ones Excel has a radio button for… it is nice to be able to easily type it.
While I can see a convenience argument for the somewhat contrived case of typing an entire file out by hand, entering the character once for the import does not seem like a great bar.

Again, that's where an IME is helpful; on the OSes I mention, it's "␞" is:
macOS: ⌘+^+Space, "record", <arrows to select>, Enter
Linux: Super+e, "record", Space, Space, <arrows>, Enter
The process is highly visual on both, so you're getting feedback about whether you're about to hit the right character, or not.
(And like, if you have the file, you can always ^C ^V the character, if say you don't know how to IME, or you don't know what the name of the char is, etc.…)
